I often come down to visit New Hampshire from around Montreal Canada and most if not every time that I visit, I take the I-89 (from the Canadian border) all the way down to the 93 and then continue further south. It's the fastest, and most scenic of routes especially I-89 through the Vermont and NH mountains.
I wanted to know however if it's worth trying to take I-91 (from the Canadian border) and then the 93 instead, therefore not using 89 at all. Only thing about this other route is that it's a bit longer in terms of miles and I've heard that it's nothing great scenery wise and can get really boring, except throughout the Franconia notch on 93, but either than that it's not the type of nice scenery that you'd get on 89. Only reason that I sometimes think of taking this alternate route is because the I-89 border crossing often gets very busy and has long delays, whereas the I-91 border crossing is a lot quieter and rarely has delays.

If you’re concerned about the line at 133/89, take a left at the flashing yellow light just before getting to the US border and follow it over to a tiny border crossing that comes into the US at route 207. You can then follow that to 78 and back to 89. It’s longer, but saves a ton of time. I wouldn’t think crossing at 55/91 would be any better than 89 as far as the wait goes.
